[SOLVED] system doesn't suspend after locking the screen

Hi,
I'm on Xfce 4.18
Lightdm 1.26.0
light-locker 1.8

My screen gets locked after the allotted time in the Power management preferences.
I have also set the system suspend time to the minimum 15 minutes.
But, the system doesn't suspend after the screen gets locked.

Do I need to give any additional info?
Can someone give some insight into this issue?

I don't prefer to use XScreensaver for the following reason.
-- I use multiple input methods. If my screen gets locked while using a non-English input method, I cannot key in my password. I am forced to restart the machine.
-- Otherwise, XScreensaver perfectly fits the bill since after locking the screen, it also suspends the system after the stipulated time.

Re: [SOLVED] system doesn't suspend after locking the screen

It would be helpful if we could see log files. If your system is based on systemd, then your journalctl log entries from around the time of the expected suspend event:

sudo journalctl -b 0 --no-pager

You could also run xfce4-power-manager in debug mode and post back the output right after when the suspend event should have taken place:

xfce4-power-manager -q
xfce4-power-manager --no-daemon --debug

And finally, to make sure you don't have conflicting screensavers daemons running:

ps -ef | grep -E 'screensaver|locker' | grep -v grep

Re: [SOLVED] system doesn't suspend after locking the screen

Can you post back the output of:

xfconf-query -c xfce4-power-manager -lv

I use Devuan -- no systemd

Where does devuan log system messages to then? /var/log/messages? If so, can you post that?

Edit: also:

xfce4-power-manager --dump

Anything related to suspend.

-- Otherwise, XScreensaver perfectly fits the bill since after locking the screen, it also suspends the system after the stipulated time.

Perhaps its an issue with light-locker? Can you uninstall it and install xfce4-screensaver and see if that works?

I'm sorry if I sound silly. Should I type the command " cat /var/log/messages | grep suspend"? If you tell me the exact keyword to be searched for, that'll be helpful.

With respect to getting xscreensaver to work with different keyboard layouts, have a read through lzack's solution at this link. They use a script to monitor the state of xscreensaver to change the keyboard layout if xscreensaver is active. You'll need to change the line:

setxkbmap us,il,us

...to match your specific keyboard layouts.

You need to have this script in the background - so once you have it worked out, add it to Settings Manager > Session and Startup > Application startup.

xscreensaver-command --watch | 
  while read MSG; do
    CMD=`echo $MSG | awk '{print $1}'`
    if [[ "$CMD" == "LOCK" ]]; then
        ##### CURRENTL=$(setxkbmap -query | grep layout | awk '{print $2}')
        echo "Locked with current layout ${CURRENTL}"
        setxkbmap us
    fi

1. here CURRENTL initialization is commented ... How will the next line be executed, since CURRENTL is not initialized anywhere else?

2. I don't mind if the keyboard input changes to English every time after screen lock. I can always switch to any other language in a moment.
So I guess I can safely make "us" as the default after resuming from the lock state. 

if [[ "$CMD" == "UNBLANK" ]]; then
        ##### setxkbmap $CURRENTL
        setxkbmap us
        echo -n "Returning to "
        setxkbmap -query | grep layout | awk '{ print $2 }'
    fi
    # echo $CMD

3. I use ibus for switching keyboard layouts. Will that matter while executing this script?
Please advise.

The value of CURRENTL will be null or a blank string. Looks like setxkbmap does nothing when a null or blank string it sent to it

2. I don't mind if the keyboard input changes to English every time after screen lock. I can always switch to any other language in a moment.

Makes sense

I don't use ibus so I'm not sure what will happen. Perhaps a test is in order?

Re: [SOLVED] system doesn't suspend after locking the screen

it works like a charm! I changed the line 

 setxkbmap us,il,us

to 

 setxkbmap us

since I don't mind changing the keyboard layout to another language after logging in from the lock screen. It hardly takes a moment.

Made the file as a executable and added to the Sessions and Startup.

Thanks ToZ. As helpful as ever!
